Body Condition Indices Predict Reproductive Success but Not Survival in a Sedentary, Tropical Bird
(PLOS, 2015-08-25)Body condition may predict individual fitness because those in better condition have more resources to allocate towards improving their fitness. However, the hypothesis that condition indices are meaningful proxies for ... -
Hunting, Exotic Carnivores, and Habitat Loss: Anthropogenic Effects on a Native Carnivore Community, Madagascar
(PLOS, 2015-09-16)The wide-ranging, cumulative, negative effects of anthropogenic disturbance, including habitat degradation, exotic species, and hunting, on native wildlife has been well documented across a range of habitats worldwide with ... -
Species, sex and geo-location identification of seized tiger (Panthera tigris tigris) parts in Nepal—A molecular forensic approach
(PLOS, 2018-08-23)Tiger (Panthera tigris) populations are in danger across their entire range due to habitat loss, poaching and the demand for tiger parts. The Bengal tiger (Panthera tigris tigris) is an endangered apex predator with a ... -
Seeing the Forest through the Trees: Considering Roost-Site Selection at Multiple Spatial Scales
(PLOS, 2016-03-30)Conservation of bat species is one of the most daunting wildlife conservation challenges in North America, requiring detailed knowledge about their ecology to guide conservation efforts. Outside of the hibernating season, ... -
A Comparative Analysis of Genetic Diversity and Structure in Jaguars (Panthera onca), Pumas (Puma concolor), and Ocelots (Leopardus pardalis) in Fragmented Landscapes of a Critical Mesoamerican Linkage Zone
(PLOS, 2016-03-14)With increasing anthropogenic impact and landscape change, terrestrial carnivore populations are becoming more fragmented. Thus, it is crucial to genetically monitor wild carnivores and quantify changes in genetic diversity ... -
Interaction between Penaeid Shrimp and Fish Populations in the Gulf of Mexico: Importance of Shrimp as Forage Species
(PLOS, 2016-11-10)This study investigated the contribution of shrimp stocks in supporting the production of valuable predator species. Fishery-independent data on white shrimp, brown shrimp, and selected fish species (spotted seatrout, red ... -
Space Use and Habitat Selection by Resident and Transient Red Wolves (Canis rufus)
(PLOS, 2016-12-21)Recovery of large carnivores remains a challenge because complex spatial dynamics that facilitate population persistence are poorly understood. In particular, recovery of the critically endangered red wolf (Canis rufus) ... -
Linear mixed-effects models to describe length-weight relationships for yellow croaker (Larimichthys Polyactis) along the north coast of China
(PLOS, 2017-02-22)In this study, length-weight relationships and relative condition factors were analyzed for Yellow Croaker (Larimichthys polyactis) along the north coast of China. Data covered six regions from north to south: Yellow River ... -
Long term monitoring of jaguars in the Cockscomb Basin Wildlife Sanctuary, Belize; Implications for camera trap studies of carnivores
(PLOS, 2017-06-28)In this study, we estimate life history parameters and abundance for a protected jaguar population using camera-trap data from a 14-year monitoring program (2002–2015) in Belize, Central America. We investigated the dynamics ... -
Breeding chronology and social interactions affect ungulate foraging behavior at a concentrated food resource
(PLOS, 2017-06-07)Prey species must balance predator avoidance behavior with other essential activities including foraging, breeding, and social interactions. Anti-predator behaviors such as vigilance can impede resource acquisition rates ... -
Delayed egg-laying and shortened incubation duration of Arctic-breeding shorebirds coincide with climate cooling
(Wiley, 2017)Biological impacts of climate change are exemplified by shifts in phenology. As the timing of breeding advances, the within-season relationships between timing of breeding and reproductive traits may change and cause ... -
Effects of biological monitoring and results outreach on private landowner conservation management
(PLOS, 2018-04-04)Sustained management efforts by private landowners are crucial for the long-term success of private land natural resource conservation and related environmental benefits. Landowner outreach is a primary means of recruiting ... -
Consequences of severe habitat fragmentation on density, genetics, and spatial capture-recapture analysis of a small bear population
(PLOS, 2017-07-24)Loss and fragmentation of natural habitats caused by human land uses have subdivided several formerly contiguous large carnivore populations into multiple small and often isolated subpopulations, which can reduce genetic ... -
Habitat selection and diurnal refugia of gray foxes in southwestern Georgia, USA
(PLOS, 2017-10-17)Understanding habitat selection of gray foxes (Urocyon cinereoargenteus) is essential to evaluate their potential response to changes in land use and predator communities. Few studies have evaluated temporal habitat selection ... -
Distributional ecology of Andes hantavirus: a macroecological approach
(2018-06-22)Abstract Background Hantavirus pulmonary syndrome (HPS) is an infection endemic in Chile and Argentina, caused by Andes hantavirus (ANDV). The rodent Oligoryzomys longicaudatus ... -
A comparison between traditional and measurement-error growth models for weakfish Cynoscion regalis
(PeerJ, 2016-09-21)Inferring growth for aquatic species is dependent upon accurate descriptions of age-length relationships, which may be degraded by measurement error in observed ages. Ageing error arises from biased and/or imprecise age ... -
Senescence and carryover effects of reproductive performance influence migration, condition, and breeding propensity in a small shorebird
(Wiley, 2017-11-15)Breeding propensity, the probability that an animal will attempt to breed each year, is perhaps the least understood demographic process influencing annual fecundity. Breeding propensity is ecologically complex, as ... -
Land Cover Change in Northern Botswana: The Influence of Climate, Fire, and Elephants on Semi-Arid Savanna Woodlands
(MDPI, 2017-10-25)Complex couplings and feedback among climate, fire, and herbivory drive short- and long-term patterns of land cover change (LCC) in savanna ecosystems. However, understanding of spatial and temporal LCC patterns in these ... -
Greywater Disposal Practices in Northern Botswana—The Silent Spring?
(MDPI, 2015-11-13)Disposal of greywater is a neglected challenge facing rapidly growing human populations. Here, we define greywater as wastewater that originates from household activities (e.g., washing dishes, bathing, and laundry) but ... -
Climate Change is Likely to Worsen the Public Health Threat of Diarrheal Disease in Botswana
(MDPI, 2013-03-26)Diarrheal disease is an important health challenge, accounting for the majority of childhood deaths globally. Climate change is expected to increase the global burden of diarrheal disease but little is known regarding ...
